I noticed the other day that the acrylic shield on my Illumina 260s are burnt directly under what I think is the UV LED. I'm running one multicolour module on each 1' fixture.

Has anyone come across this before?

Thanks,

I had exactly the same problem under the uv leds. The acrylic eventually cracked and moisture got in and damaged the boards. Change the acrylic. They are expensive so I got some uv resistant acrylic cut to size for a fraction of the price. I bet over time they will end up the same but itís much cheaper
